Converting a lower quality 32khz to a better 44.1khz will always tend to produce a "birdie" sound as you describe it.
I would try looking at filters, effects etc in audio editors like CoolEdit 2000, Sound Forge, Goldwave, DartPro, etc, etc that hopefully can filter out a lot of the induced noise and improve the overall quality. Demux the MPEG2 file and then use the MP2 audio file as above. If you make any improvents, remux back with the M2V file. Most of the editors I mentioned above will only use WAV files so that fine, when you do the final save, save as a WAV and convert it back to MP2 audio with TooLame (h**p://members.dingoblue.net.au/~mikecheng/ )
